The Department of Defense (DOD) owns many offshore platforms in various worldwide locations. These platforms are presently being utilized for training and long term research and development testing. History indicates the offshore platforms have not been inspected or maintained as well as on-shore base facilities because there is not a standard inspection or maintenance manual for them. The Chesapeake Division, Naval Facilities Engineering Command, Ocean Engineering and Construction Project Office (FPO-1) is developing the `Offshore Platform Inspection, Maintenance, Repair, and Rehabilitation (IMRR) Program' to assist the DOD with the life cycle ownership of offshore platforms. Each DOD offshore platform owner will be able to use the IMRR program to plan and execute periodic offshore platform operations. The program will address the procedures for the preparation of a data base, inspection, maintenance, repair, and rehabilitation/reverification. The IMRR program will incorporate new developments being made in nonlinear analysis, inspection and repair equipment and procedures, and risk and structural reliability analysis.
